Defensive publication

ABSTRACT

WHEREIN EACH R&#34; IS A SUBSTITUENT SELECTED FROM THE GROUP CONSISTING OF A HYDROGEN ATOM, A HALOGEN ATOM, AND AN ALKYL RADICAL CONTAINING FROM 1 TO 4 CARBON ATOMS, R&#39;&#39;&#39;&#39;&#39;&#39; IS THE RESIDUE OF A BIFUNCTIONAL CARBOXYLIC ACID PRECURSOR HAVING UP TO 40 CARBON ATOMS AND IS SELECTED FROM THE GROUP OF PRECURSORS CONSISTING OF CARBONIC ACID AND DICARBOXYLIC ACIDS, AND X IS A GEM-BIVALENT RADICAL HAVING A SATURATED POLYCYCLIC THREE-DIMENSIONAL STRUCTURE WHICH INCLUDES A SATURATED BICYCLIC ATOMIC BRIDGED HYDROCARBON RING MEMBER. COMPOSITE ASSEMBLIES COMPRISING AT LEAST TWO STRUCTURAL MEMBERS BONDED TOGETHER BY AN ADHESIVE MEMBER COMPOSED ESSENTIALLY OF A POLYMER OF A BIFUNCTIONAL CARBOXYLIC ACID AND A BISPHENOL, SAID BISPHENOL HAVING THE FOLLOWING GENERAL FORMULA:

DEFENSIVE PUBLICATION UNITED STATES PATENT OFFICE Published at the request of the applicant or owner in accordance with the Notice of Dec. 16. 1969, 869 O.G. 687. The abstracts of Defensive Publication applications are identified by distinctly numbered series and are arranged chronologically.

Defensive Publication applications have not been examined as to the merits of alleged invention. The Patent Oifice makes no assertion as to the novelty of the disclosed subject matter.

PUBLISHED JUNE 1, 1971 lowing general formula:

RI! RI! I zl! fill wherein each R is a substituent selected from the group consisting of a hydrogen atom, a halogen atom, and an alkyl radical containing from 1 to 4 carbon atoms, R is the residue of a bifunctional carboxylic acid precursor having up to 40 carbon atoms and is selected from the group of precursors consisting of carbonic acid and dicarboxylic acids, and X is a gem-bivalent radical having a saturated polycyclic three-dimensional structure which includes a saturated bicyclic atomic bridged hydrocarbon ring member.
